1. If you're installing a replacement VFD control box, install new unit with the M8 Hex Flange Nuts removed in a previous step. Otherwise, see #2.
2. Attach the VFD control box to the leg kit using M8 x 25mm Set Screws D , M8 Hex Flange Nuts E , and M8 Roll-in T-Nuts F .

2. Spindle Motor¶

Parts List¶

Tools List¶

2.1 - Remove Existing Spindle¶

2.1.1¶

1. Disconnect the M23 cable from the existing spindle. If you have a router mount, unplug your router and remove it from the mount.

2.1.2¶

1. Remove the existing spindle or router mount from the machine by removing the screws connecting the base adapter to the tramming plate. Save hardware for installation of the new spindle.

2.1.3¶

1. If you have a spindle, remove the base adapter from the spindle. If you have a router mount, remove the mount from the base adapter.

   • Depending on your spindle/router configuration, your Base Adapter will be either CRP144-23 or CRP144-33. The part number is engraved on the Base Adapter, as shown.

2.2 - Install Spindle¶

2.2.1¶

1. Insert the M8 x 30mm Hex Cap Screw B into the hole on the Base Adapter as shown prior to installing Base Adapter on the spindle. The location is identical for all Base Adapter models. This screw will be used in a later step.
2. If you are reusing fasteners that were previously removed, this Hex Cap Screw is a replacement for the original fastener at the indicated location.

2.2.2¶

1. Install the base adapter on the back of the Spindle H, using the provided:
   1. six M8 x 20mm Socket Head Cap Screws A for Base Adapter CRP144-23
      1. Tighten the M8 fasteners to 13-15 ft-lb (17-20 Nm).
   2. four M6 x 20mm Socket Head Cap Screws C for Base Adapter CRP144-33
      1. Tighten the M6 fasteners to 62-70 in-lb (5-6 ft-lb, 7-8 Nm).

2.2.3¶

1. Install the Base Adapter (attached to the spindle) onto the tramming plate using an M8 Shoulder Bolt D, M8 x 30mm Socket Head Cap Screw E, M8 x 30 mm Hex Cap Screw previously inserted through base adapter, and M8 x 35mm Socket Head Cap Screw F, and Eccentric Bushing G. With the exception of the Hex Cap Screw, this hardware is reused from when you removed the spindle from the machine.

Tools List¶

3.1 - Install Air Regulator¶

1. Install the Air Regulator A on the inside front face of the electronics bar using M6 x 12mm Socket Head Cap Screws B and M6 Roll-in T-nuts C.

3.2 - Prepare Spindle Air Connection¶

1. Cut the 6mm Hose D (shorter segment) into two equal lengths.
2. Insert the two pieces of 6mm Hose D into the fittings on the top of the box located at the front of the spindle motor.
3. Insert the free ends of the hose segments into the 8mm to 6mm Wye Fitting F.

3.3 - Air Hose and Cable Routing¶

3.3.1¶

1. Prior to routing cables through the cable track, it is recommended to open each cable track link using a small screwdriver.

3.3.2¶

1. For systems where an existing spindle controller is being replaced, remove the existing M23 cable from the machine.
2. Route the new M23 Cable G as indicated. The path is identical to the M23 cable you removed.

3.3.3¶

1. Route the 8-pin M12 Cable, 28' H and 8mm Hose E as indicated. The path is identical to the M23 cable routed in the previous step, if applicable.
2. Connect one end of the 8mm Hose E to the 8mm to 6mm Wye Fitting at the spindle and the other end to the Air Regulator.
3. Supply air to the Air Regulator and set the pressure to 105 PSI (functional range: 95-115 PSI).
4. Connect one end of the 8-pin M12 Cable H to the corresponding panel mount on the spindle and the other end to the 24V Wall Adapter I.

3.3.4¶

1. Connect your M23 cable to the spindle.
2. Carefully check that the machine has full range of motion and there is no strain on your new connections.

3.3.5¶
